Although microfinance programs were born with the specific objective of reducing poverty, currently they attend to small entrepreneurs who have limited access to traditional finance, but are not necessarily poor. These small entrepreneurs are key agents of any territory due to their capacity to create jobs, incomes and to strengthen the local entrepreneurship structure. Many studies have tried to measure the impact of microfinance programs. Preliminary results suggest that microfinance programs could be an effective instrument of local development. However, more studies have to be conducted to support this hypothesis. The objective of this work is to evaluate the impact of a microfinance program that provides microcredit on the income of microentrepreneurs in the Araucania Region in Chile. A non-experimental, cross-sectional study with a control group was carried out using the matched comparison method, using the propensio score technique. The results suggest the existence of a plausible association between participating in a microfinance program and higher incomes in local microentrepreneurs.
